摘　　要：对２２例生育者、４４例精索静脉曲张（ＶＣ）患者、１７例特发性无精子症（ＩＡ）患者行远红外阴囊测温。并对无精子者行睾丸活检。结果发现：（１）ＶＣ患者阴囊温度显著高于生育者（Ｐ＜０．００１）而低于ＩＡ（Ｐ＜０．００１）。（２）ＶＣ精液正常者阴囊温度与生育者无差异而显著低于ＶＣ精液异常者（Ｐ＜０．０１）。（３）ＩＡ与ＶＣ合并无精子症阴囊温度无显著差异。（４）阴囊温度升高使生精细胞减少，精子成熟障碍，特别是Ｓｅｒｔｏｌｉ细胞变性明显。认为ＶＣ、ＩＡ患者均存在阴囊温度升高，且温度愈高，睾丸生精功能愈差。Ｓｅｒｔｏｌｉ细胞变性是睾丸生精障碍原因之一。阴囊温度调节失调可能是阴囊温度升高的直接原因。Scrotal temperature was measured in 22 fertile men, 44 varicocele patients and 17 idiopathic azoospermia with infrared scrotal thermography. The testicular biopsies were performed in all of the azoospermia patients. The results showed that the scrotal temperature values of varicocele patients were significantly higher than those of fertile men(P<0.001), but lower than those of idiopathic azoospermia(P<0.001). The temperature of varicocele patients with normal semen were identical to those of fertile men, but lower than those of varicocele patients with poor semen(P<0.001).The temperature of idiopathic azoospermia did not significantly differ from those of azoospermia with varicocele. The testicular biopsy showed the decrease of spermatogonia, the dyszoospermia and the degeneration of Sertoli cell. It suggests that the higher the scrotal temperature, the poorer the semen. It is the thermoregulatory dysfunction of scrotum that might lead to scrotal hyperthermia.
